A tunneled planing craft is a high-speed boat with two tunnels over the hull bottom that are designed to improve vessel’s performance. Hydrodynamic performance of hulls in calm-water well-known, however, current information on wave conditions limited. In this study, different degrees freedom heave and pitch motions studied regular waves by using computational fluid dynamics (CFD) method based U...

Periodontally affected root surfaces are hyper mineralized, and contaminated with cytotoxic and other biologically active substances especially endotoxins which play a pivotal role in preventing new connective tissue attachment to the exposed root surface. Following root planing the instrumented root surface is invariably covered by smear layer containing remnants of dental calculus, contaminat...

Waste management involves an efficient planing of collectionvehicles and corresponding crews. We present an optimization model and algorithm for the crew scheduling problem which is the second part of an integrative solution approach. We differentiate between a network based duty generation phase and a duty optimization phase where an optimal set of annual duties for all employees is selected.
